Is it possible to switch-off the preservation of the file timestamps (access and modification times) on file copy?

Hello samba gurus

Samba start using the utimes() call to preserve the access and 
modification times of the transferred file. This change happens 
somewhere between the 3.0.2 and 3.0.14 where I did not investigated it 
exactly. Evaluating this problem some time ago I have found this 
behavior can not be changed by any of the configuration option. Am I right?

Case can be the storage of the huge DVD images running on the multi-node 
filessytem (SAM-QFS for instance) accessed via the Windows Explorer. 
Win.Explorer is copyingthe files in 64k blocks setting the time-stamp of 
the target file on every block transfer. utimes() operation seems to be 
much more time consuming on the multi-node filesystem which keeps the 
consistency of such timestamps  between the single nodes. This is making 
the copy operation extremely slow in comparison of the usage of the 
simple filesystem nor the usage of the "copy" command line utility.

I suppose the simple option:

 "preserve timestamps = [yes/no]"   (default: yes)

can fix this problem. Is there anybody who also supports such "feature"?
